5 Claims.

This invention relates to le envelopes and the object of the invention is to provide an envelope in which booklets, stock records, order blanks or other printed matter may be mailed, the device being arranged so that the ilap carries the letter concerning the mailed material and the envelope carries the material, the letter being separable from the envelope and when separated leaving a iile envelope with a ling tab carrying indicia as to the contents of the envelope.

One of the particular objects of the invention is to provide an envelope which may be utilized in mailing third class matter and having a ap separable from the envelope to provide a filing pocket having an extending index tab on which indicia may be printed.

A further object of the invention is to `provide an envelope of the character described which may be readily opened by the postal authorities for inspection.

Another object of the invention is to provide an envelope having a pocket for printed matter and having a flap carrying a letter concerning the printed matter, the said flap being foldable to provide a closure for the pocket and the material of the envelope being perforated so that the letter flap may be separated therefrom, the perforations being arranged to leave a tab attached to the pocket, said tab carrying indicia concerning the contents of the pocket and the pocket and index tab being usable as a file pocket in a ling cabinet.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred forni of construction by which these objects are attained is shown in the accompanying drawing in Which- Fig. 1 is a perspective view of a file envelope, embodying my invention, ready for mailing.

Fig. 2 is a perspective view showing the le envelope open for inspection.

Fig. 3 is an elevation of the ijle pocket after the letter ap has been separated therefrom.

Fig. 4 is an enlarged section taken on line A-A of Fig. 3.

The device is formed from a paper sheet and comprises a center section having integral end flaps 1 as shown in Fig. 2. The portion 2 is foldable on the center section as shown in Fig. 2 and the flaps 1 are turned thereover and glued to the portion 2 thus forming a pocket in which pamphlets or other printed matter 3 may be inserted. The letter ilap 4 is folded on the (Cl. 12S-16.7)

dotted line 5 to form a closure flap for the le pocket and the letter flap is provided with an aperture 6 having a re-enforcing member 7 thereabout through which the metal clasp 8 may be inserted. This metal clasp 8 is secured in the portion 2 of the envelope and provides a means for closing the envelope as will be understood from Fig. 1. The center section of the envelope is provided with a series of perforations 9 on a line parallel with the top and bottom of the envelope and spaced from the fold 5 on which the letter flap folds over the portion 2. The perforations 9 are carried through to an index tab 10 formed by the die cut slots 11 at the edges and by the perforations 12 at the top which are coextensive with the fold 5 of the letter ap.

In use the letter flap provides a space on which a letter may be written concerning the contents of the le pocket. The pocket may contain order blanks, cards, folders, sales pamphlets, advertising matter or any other matter of similar nature which can be conveniently placed in the envelope. The portion 2 of the envelope pocket also lists the contents of the pocket on the face thereof and the ilap 4 when folded over the pocket is secured in place by the clasp 8 as shown in Fig. i. The outside of the flap 4 carries the return address of the company mailing the envelope together with sales slogans or contents of the envelope. This side of the flap 4 shown in Fig. 1 is also utilized for the address of the person to Whom the envelope is sent. The receiver upon opening the envelope may read the letter on the inner face of the ap 4 concerning the contents of the le pocket and if the con-- tents are to be kept for future reference the user tears the letter flap 4 off on the perforations 9 and 12 which Will leave the index tab 10 extending upwardly from one edge of the le pocket. This index tab refers to the contents of the iile pocket and the le pocket may be placed in a standard file cabinet under the proper index. In this manner, the contents of the le pocket are always available for future reference and thus insures the receiver having the material at hand when the need arises.

From the foregoing description, it becomes evident that the device is very simple and erlicient in operation, is very useful in iiling the contents for future reference, is readily accessible in a le and provides a device which accomplishes the objects described.

Having thus fully described my invention, its

utility and mode of operation, what l'. claim and desire to secure by Letters Patent of the United States is- 1. In a file envelope, a paper sheet arranged to provide a rectangular pocket open at one side, the sheet being provided with a fold line in spaced relation with the open side ofthe pocket to provide a flap foldable over the pocket to close the same, the sheet being also provided with perforations extending parallel to the fold line between the fold line and the open side of the pocket, the perforations at one side of the sheet extending upwardly to the fold line to provide an index tab having an upper edge coextensive with the fold line and the iiap being separable from the pocket along the perforations to leave the index tab extending above the open side of the pocket.

2. In a le envelope, a paper sheet arranged to provide a rectangular pocket open at one side, the sheet being provided with a fold line in spaced relation with the open side of the pocket to provide a flap foldable over the pocket to close the same, the sheet being also provided with perforations between the fold line and the open side of the pocket and extending parallel with the fold line, the perforations being arranged to provide an index tab having an upper edge co-extensive with the fold line and the flap being separable along the perforations with the index tab extending above the open side of the pocket. i
